What, you mean you weren't aware that there was a major rift between these two style stars? Well, read on til truth makes all things plain.

Here's what happened. Chloe Sevigny gave an interview to Playboy (first odd thing) in which she declared that she hated modern "It" girls.

Today the term is used to describe, say, Peaches Geldof - a girl who doesn't do anything but is just sort of around...The original It girl was the 1920s movie star Clara Bow; then in the 1960s, with Edie Sedgwick and (Andy) Warhol, It girls turned into socialites, ladies of leisure, people who had it just for being fabulous. But Edie was just a rich drug addict, and when I got called the It girl everyone thought I was that too... I felt I was doing stuff, not just being a socialite.

Peaches, understandably, took this amiss, and the It Girl author/designer took to Twitter to give Chloe a schooling in classy restraint.

But what of the rest of us? What real reason, Peaches?

Tempting as it is to ascribe the rift to a major disagreement over #mooreandme, MM is probably Matthew MacCaulay of A.R.E. Weapons, Chloe's boyfriend of 8 years and...I guess?...somehow connected with Peaches in some way we'd probably be better aware of if we kept up with her love life! But in the end, she's philosophical.

That's telling her. We'd have thought she'd have a thicker skin about the whole "does nothing" charge, but Chloe is a major Cool Girl so the slight must hurt. The bigger question is why no one's jumping to Edie Sedgwick's defense...at the very least, Sienna Miller.
